Renewed July 29, 1932 9 Claims.

The principal object of this invention is to provide means for feeding the paper into a printing press which will be of the narrowest possible design so as to take up the least floor space in a printing establishment, so as to permit the placing of press units of the narrowest possible design much closer together than has been possible heretofore; and to provide a press which in itself will require the least possible space.

,Other objects and advantages ofthe invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. 1 is a side view showing four units of a printing press with the paper supplying means arranged in accordance with this invention;

Fig. 2 is an end elev tion with parts in section;

Fig. 3 is a plan of the web supplying mechanism for the four units; and

Fig. 4 is a view similar to Fig. 2 showing the way the invention can be employed with a narrow web.

It is well known that the units of a press take up much less room in one direction than the paper reels that are required to feed them. The factor controlling the maximum number of units that can be placed in a given floor space is not the size of the press units themselves, but the space taken up by the reels which have to be used in conjunction with them. This invention relates to the location of the reels in the narrowest possible space so as to permit the placing of the press units closer together than has been done before.

This method of feeding the paper is shown in the drawings as applied to a series of press units, which themselves are of minimum width because of the arrangement of the printing couples and inking mechanism. Each unit has four printing cylinders 10 arranged in vertical alignment, that is, with their shafts all in a vertical plane. The

two inking motions 11 that are required are located one at the top and the other at the bottom 4 beyond the top and bottom cylinders of the two couples. In this way it will be clear that the width of a single printing unit is not much wider than the diameter of one of its printing cylinders.

In a previous application, Serial No. 451,965, filed May 13, 1930, I have shown a new method of feeding paper into a press comprising the placing of the paper rolls in a vertical position on end, and the transporting of the paper rolls around case, however, each roll is treated separately.

In the present case that method is used, but

the printing plant in vertical position. In that instead of separate rolls, a reel is employed carrying a plurality of rolls. The reels themselves are stood onend and have means for carrying the rolls of paper into and out of feeding position.

As shown, each reel comprises a central shaft 12, top and bottom arms 13 carried by the central shaft, and in this case, two reel shafts or sets of studs 14 mounted on these arms at equal distances from the central shaft. The rolls of paper 15 are mounted on these studs 14. -The bottom of the central shaft is mounted in a bearing 16 which may be located on the floor or in any other convenient position, and there is a bearing 1'7 for the shaft 12 directly above it located on the frame 18 of the printing press.

It will be noted that this shaft 12 is located at the side of the press, but at a distance from it substantially the same as the radius of the roll of paper when applied to the reel. In this way it takes up very little room.

On the frame 18 of the press is mounted a motor 20 which by means of reducing bearing 21 directly drives the shaft 12. This is a very simple arrangement and provides for the rotation of the reel to bring a fresh web roll into running position. The rolls can be transported around the plant on end and a fresh one mounted on the reel while the running roll is supplying web to the press. The reel can be turned by the motor when it is time to make a paster or change from one reel to the other, so as to bring the running roll into the position shown in Fig. 3.

Tension is maintained on each roll by a series of flexible straps 22 stretched across from one side to the other of arcuate arms 23. These arml are pressed toward the roll by springs 24 which are located under the printing press, and the arms are pivotally mounted. The straps 12 are fixed to one end of these arms and the other end passes over guide rolls 25 on the arms and are connected with springs 26 which are adjustable, so as to provide whatever tension may be desired.

The web passes over a vertical guide roll 28. The side register of the web is accomplished by a diagonal inclined turning bar 2'7 which can be moved in such a direction as to secure the desired register. This simplifies the reel construction as the bottom half of the paper roll is almost on the same level as the bottom of the tuming bar.

When a roll of paper less than full width is used the web can be led to either side of the printing couples by manipulation of, the turning bars. vA short turning bar 29 is shown in Fig. 4

It will be observed that the room taken by each reel is about the same as that taken by two press units. 'For this reason the reels are located on opposite sides of the press and staggered in such a manner that there is enough space for the number of reels required, and they are placed as close together as is practical. Reels on both sides of the press are, of course, fed from their respective sides. By the staggered relationship the reels on opposite sides of a single press unit are located practically within the space occupied by the press unit, but one at one side of the center of a pair of units and the other at the opposite side of the center to feed two units. In this way. a given area of floor space can be made to contain a larger number of printing press units than has been the case heretofore, and in other cases excessive crowding of a press room can be avoided.

Although I have illustrated and described only two forms of the invention I am aware of the fact that changes can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited to the forms shown, but what I do claim is:-

l. The combination with a press unit, of a vertical web roll reel located below the unit but a little to one side thereof, and means for rotating said reel on a vertical axis to bring a fresh web roll thereon toward the press into running position.

2. The combination with a printing press, of a reel for a plurality of web rolls located entirely under the press with the axis of the reel in a vertical position, and a vertical guide roll in position for guiding the web from the web roll into the press.

3. The combination with a printing press, of a rotatable reel for the web rolls located below the press and to one side thereof in a position to support the web roll with its axis vertical, means for guiding the web directly under the press laterally, means for turning the web and changing its direction from horizontal with the web vertical to a position in which the web runs substantially vertically and upwardly into the printing couples of the press, and means for rotating the reel on a vertical axis to move a web roll toward the press.

4. The combination with a press frame and a perfecting press unit located on the frame, of a motor on the frame, a vertical shaft below the press unit, a reel carried by said shaft for supporting a plurality of web rolls, means for rotating the shaft from the motor, and means for guiding the web in vertical position under the press and then upwardly into the press.

5. The combination with a printing press, a reel for the web rolls rotatable on a vertical axis, and means for guiding the web into the press from below, of yieldingly mounted tension arms, tension straps extending horizontally and carried by said arms, and yielding means for holding the straps taut against the running web roll.

6. In a printing press, the combination with two printing units, of two vertically disposed web roll reels for supplying the web to the two units, one reel being located at each side of the press in staggered relationship, for the purpose described.

7. In a printing press, the combination of a reel for the web rolls located vertically so that the rolls can be mounted on it with their axes vertical, of a press unit mounted above the reel and to one side thereof and consisting of four cylinders located in vertical alignment.

8. In a printing press, the combination with four cylinders constituting two printing couples located in vertical alignment, of means for supporting paper rolls mounted with axes vertical for feeding the couples.

9. In a printing press, the combination with a press unit, of a rotatable reel for a plurality of web rolls, the axes of said web rolls being vertically disposed.
